Metal. In the picture they look more glossy than in person. The core support is a good reference for how it looks.Are those metal or plastic fender liners? If plastic did you epoxy those too?
How does one control the gloss?Here is my engine compartment in black epoxy.
About 60% gloss
I made no attempt to control the gloss. the "60% gloss" is just my estimate of what it is. It looks very similar to some parts I had powder coated at that gloss level.How does one control the gloss?
Well that ain't no 283
